Chicago is served primarily by two major airports with distinct roles. O’Hare International (ORD) is a large international hub handling many long-haul and transcontinental flights and is commonly used by legacy carriers, so fares can range from budget-competitive to premium depending on route and timing. It sits about 17 miles northwest of downtown; the Blue Line CTA rail connects downtown in roughly 45–60 minutes for a modest fare, while taxis and rideshares typically take 30–50 minutes and cost substantially more. Midway (MDW) is a smaller, more budget-leaning airport to the southwest about 10 miles from the Loop, with a quicker 20–30 minute ride by Orange Line and generally lower-cost domestic service from low-cost carriers. O’Hare offers broad connectivity but can be busy and sprawling; Midway is more compact and often easier for quick domestic turns, though with fewer international options.

Detroit Metropolitan Wayne County Airport (DTW) is the region’s primary international hub, typically serving a mix of full‑service carriers and several major domestic airlines, with some low‑cost options on key routes. It sits about 20 miles (roughly 30–45 minutes by car) southwest of downtown Detroit; ride‑shares, taxis and shuttle services are common, plus express buses and rental cars—expect transit fares or shuttle fees generally in modest ranges and higher taxi/ride‑share costs depending on traffic. DTW is usually convenient for connections and offers extensive amenities, though security lines and travel times to the city can be a drawback during peak hours. For some budget‑minded flyers, nearby smaller airports can be a cheaper but less connected alternative.

The cost of a one-way flight from Chicago to Detroit ranges from $100 (October 2026) to $166 (December 2026). On average, the ticket price is about $130–$291.
